Telecom trends 261112

  1. 1. Telecom Trends Sharon Rozov CTO Team Nov. 2012
  2. 2. The New Telecom Applications Devices/Big Data Machines Network Cloud
  3. 3. ApplicationsAutomating our lives; Streamlining our daily routines Video Augmented Location Delivery Reality Smell over IP services Social 3D Messaging Conferencing Networking Printing
  4. 4. Devices/Machines A bridge between the tangible and virtual worlds The vision: 50 Billion connected devices in 2020 Any tangible device (refrigerator, washing machine, car, etc.) Sensors/Actuators: installed, implanted (animals), wearable (humans) The mobile phone as a hub for sensors RFID
  5. 5. Big Data Devices + Data = Applications Everything we do generates data  2.5 quintillion (2.5*10^18) bytes of data are created daily  The amount of data in the world doubles every 18 months  Example data generators: social networks, internet search indexes, call detail records, astronomy, atmosphere, genomics, military surveillance, medical records, photography archives, e-commerce BIG DATA challenges  Volume, Velocity, Variety, and Veracity Types of data  Usage data  Volunteered data Data processing  Mining, analytics – find patterns in data  Semantics – decode ‘meaning’ of data
  6. 6. Cloud The Cloud makes applications global The Cloud enables allocation of compute and storage resources on-demand Follow-me cloud: global access, multi access, multi device The Cloud runs  Applications  Data mining/analytics/semantics  Network functionality  Compute/storage offloaded from end-devicesCentralization Centralized Cloud: Distributed Cloud / Fog Computing: - Global Service - Low-latency - Large capacity, elasticity applications/content Distribution - Ultimate utilization of - Saves networking resources resources - Opportunistic computing, based on available capabilities of devices/CPEs flexible apportioning
  7. 7. Network Content Centric Networking Move the focus from network nodes to:  Delivery of content objects  Delivery of messages to/from devices (Publish-Subscribe) The changing relationship between network and services The network establishes network resources connectivity, applications Service-aware traffic as building blocks running steering that can be used to Over The Top ‘program’ new services
  8. 8. The Internet of Things (IoT), the Internet of Everything (IoE) Building a networked society ‘Things’ will be seamlessly integrated into the information network ‘Things’ are expected to become active participants in business, information and social processes Things’ reacting autonomously to ‘real/physical world’ events and influencing it by triggering actions with or without human intervention Logical entities: Persona, Community, Things Streamline everyday tasks, processes Context: Automate decision making Ownership, Authorization , Location Tackling life inefficiencies Access to covert information Better recommendation engines Physical entities: Human, Machine/Device /Object
  9. 9. Network evolution towards the ‘New Telecom’ Major directions in Telecom Networks Intelligence is moving to the cloud Complexity is moving to the edge Networks are flattening – from hierarchy to mesh architecture Network architecture convergence Networks automation, flexibility
  10. 10. Wireless takes it all Wireless in the frontend, wireline in the backend In 2016 wired devices will account for 39% of IP traffic, while Wi-Fi for 51% of IP traffic and mobile devices for 10% of IP traffic (source: Cisco VNI, May 2012) LTE (Long Term Evolution) (3.9G)  As of Nov 2012, LTE is deployed in 117 networks in 54 countries, with 323 operator commitments (source: 4G Americas, Nov 2012)  More than 40M subscribers today, projection for 1B LTE subscribers by 2017 (source: Informa Telecoms, June 2012) LTE-A (4G) : expected to be commercially available in 2013, with wider deployments by 2015 WiFi WiFi WiFi (self deployed, operator deployed, managed WiFi) TV White Space – for rural broadband Beyond LTE-A (LTE-B, 5G) – Standardization (3GPP release 12 is underway) Personal Area Networks  ZigBee, Bluetooth The LTE packet core architecture (EPC) is designed to support both fixed and mobile access networks and become a common converged core
  11. 11. Heterogeneous Networks (Hetnets) Macro Cell for coverage, Small Cell for capacity Higher data rates and increased capacity require denser infrastructure User distribution and traffic density are often non-uniform  deploy an heterogeneous network (hetnet): hotspot cells in traffic hotspots Hetnet complexities:  cell density  interference management  user-deployed cells handled through automation: Self Organizing Networks (SON)
  12. 12. Content is pushed to the Edge The popularity of content-rich applications and availability of smart compute-extensive devices, drive content and applications to the edge Storage/caching pushed into network nodes, as close as possible to end-users; network steering to retrieve content  In the future – smart terminals will become part of an opportunistic cloud trade-offs between storage/computing/communication  Currently for optimization of overloaded networks, performance and QoE guarantee  In the future – optimization of energy consumption
  13. 13. Networks are flattening Hierarchy is breaking down Network flattening is achieved through removal of aggregation points The network is simplified to include two types of connections  Access to cloud centers (centralized or distributed)  Inter-connectivity between cloud centers Ultimately the network will become a symmetric mesh Each entity connected to the network (device/machine/cloud) can be a content client or a content server
  14. 14. Mesh Architectures Breaking down network’s hierarchical architecture Cloud Federation  Connect between distributed cloud centers to enable access to content Mesh connectivity between base stations  LTE/LTE-A introduces new spectrum efficiency mechanisms (e.g., COMP) that involve coordination between base stations. This calls for mesh connectivity (over x2 interface) between e- NodeBs Device to device (D2D) Communication  Beyond-LTE standards will probably enable device-to-device communications  Useful in scenarios like content sharing with friends in the close proximity, cognitive cars exchanging road information
  15. 15. Network Virtualization: the network wanders to the cloud IT-Telecom Convergence Network Function Virtualization (NFV) – virtualization of network functions and services  Motivation: run network functionality over off-the-shelf standard IT infrastructure  leveraging standard IT virtualization technology to consolidate many network equipment types onto industry standard high volume servers, switches and storage  applicable to any data plane packet processing and control plane function in fixed and mobile network infrastructures Software Defined Networking (SDN) – separation of Network node Control and Data planes, with an open interface (e.g., OpenFlow) between them  Motivation: network programmability - turn network resources into building blocks that can be used to ‘program’ new services  Intelligence is moved to the cloud, network is simplified and can handle capacity growth and scale  Control plane is implemented in software and running in the cloud  Network nodes specialize in efficient ‘forwarding’ (data plane), will be commoditized and become cheaper
  16. 16. Content/application aware networking The network receives new roles A ‘connectivity’ network will always be there The ‘delivery’ network  Optimized content delivery per user/application requests  Message Clearing house (Publish Subscribe)  Service Orchestration – mashup applications and data originated in various verticals
  17. 17. Telco Operator role Telcos will be reinventing themselves Choose your role!  Up the value chain or down the value chain • Bit carrier Connectivity • Connectivity brokerage services • Content delivery, message delivery Delivery • Service Enablement • Linking content and information into Service something meaningful • Localizing a global service
